Question

The wings of a mosquito vibrate 240 times in a second. Find the frequency and time period of vibration

Answer 1

♥HEY DEAR .♥

Frequency :- no. of vibration in 1 sec

so 240 is the frequency of that mosquito wings.

time period :- 1 / frequency of wave

= 1/240 = 0.04166.....

HOPE ITS HELPFULL

BE BRAINLY

Answer 2

Given : A pendulum oscillates 240 times in a seconds.

　

To find : What is its time period and frequency?

　

Using formula :

1) Frequency = Number of times the pendulum oscillates/Total number of time taken.

　

2) Time period = Number of oscillation per second/Frequency.

　

Calculations :

→ Frequency = 240/1

→ Frequency = 240 hertz

　

→ Time period = 1/240

→ Time period = 0.00416666667 seconds

　

Therefore,

1. Frequency = 240 hertz.
2. Time period = 0.00416666667 seconds.
